| The ECU expects the solenoid to provide around 28-33 Ohms resistance. If you use a solenoid with too little resistance (or draws too much current under any condition), you run the risk of [[driver01|blowing the ECU's internal driver]]. | The ECU expects the solenoid to provide around 28-33 Ohms resistance.

| + | The one 3-port solenoid that we've tested to work well without any modification or restrictor setup is made by Ingersoll-Rand. It's Aro model number P251SS-012-D. You can find this solenoid on [[http://www.grainger.com/Grainger/INGERSOLLRANDARO-Solenoid-Valve-6JJ52|Grainger's site]] by searching for that part number or Grainer's part number 6JJ52. | ||

| The factory boost control solenoid (BCS) does actually work, but it's only a 2-port solenoid. Which means you'll need to wire it up with a restrictor (we've found that a 0.025" restrictor works well) similar to the stock configuration and you'll need to remove the internal restrictor found in the stock BCS itself. | The factory boost control solenoid (BCS) does actually work, but it's only a 2-port solenoid.

| - | The one advantage here is that you can plug the solenoid directly into the factory harness without need for cutting and soldering wires into place. You'll just spend some time locating an appropriate restrictor "pill" from somewhere. These are probably readily available, though. Just search for "EVO" boost pills or something similar. | + | The one advantage here is that you can plug the solenoid directly into the factory harness without need for cutting and soldering wires into place.

These solenoids either hang open or get locked closed (depending on configuration) under high boost conditions, making them unsuitable for this application. | + | The factory EGR and fuel pressure solenoids are options, but do not seem to work properly much above 25psi.
